Dear Dejan,<br><br>Thanks for your reply.<br><br>I reviewed the log of tibcodb2 and noticed that after step7.ServerB reboot, ServerB CAN heard from ServerA.<br><br>The strange thing is that when ServerA reboot, ServerA CANNOT heart from ServerB.

Why ServerA cannot recognize ServerB, but ServerB can recognize ServerA ?<br>Is that means something such as a firewall or the network switch port restrict some kind of packet to send from ServerB ?<br>I'm curious about the way how suse cluster nodes communicate with each other.<br>
Can you point the way to shed me some light ?<br>Thanks.<br><br><br><div class="gmail_quote">2010/6/9 Dejan Muhamedagic <span dir="ltr"><<a href="mailto:dejanmm@fastmail.fm">dejanmm@fastmail.fm</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

</div>According to the logs, the tibcodb never heard from the other<br>
node after reboot. That's strange. You sure you don't run<br>
firewall? Or something else preventing packets reaching the node.<br>
